Yes, you're correct.

Keith sold half of his comic books and then bought 8 more he now has 12 how many did he begin with

To find out how many packages of used and new comic books Amy bought, let's break down the problem step by step.

First, you correctly mentioned that the comic book store sells used comic books in a package of 5 and new comic books in a package of 3.

Now, let's determine the number of used comic book packages Amy bought. Since each used comic book package contains 5 comic books, we need to divide the total number of comic books purchased (16) by 5:
16 ÷ 5 = 3 with a remainder of 1

So, Amy bought 3 packages of used comic books, which accounts for 3 x 5 = 15 comic books.

Next, we need to find the number of new comic book packages Amy purchased. Since each new comic book package contains 3 comic books, we can subtract the remaining 1 comic book from the total number of comic books:
16 - 15 = 1

Therefore, Amy bought 1 package of new comic books, which includes 3 comic books.

In conclusion, based on the given information, Amy bought 3 packages of used comic books and 1 package of new comic books.
